Avnan is introducing our new fan coil controller platform, another example of our electronics and application design expertise. This advanced platform combines intelligent control, monitoring, and diagnostic capabilities to deliver reliable smart HVAC solutions for OEM customers. Avnan’s fan coil controller platform consists of two key parts: the advanced control board that manages the various functions of the system and the mobile app that provides data insight into its performance, allowing field technicians to help monitor, diagnose and troubleshoot any operational issues with the fan coil system. This HVAC monitoring system provides real-time performance insights, allowing technicians and OEMs to quickly identify issues, improve troubleshooting, and optimize system operation.

Fan coil units (FCU) are crucial components in HVAC systems, designed to regulate indoor temperature efficiently. A unit is basically comprised of a fan and a heat exchanger (coil) to either cool or heat air, ensuring optimal thermal comfort in residential, commercial, and industrial spaces. These systems are widely used due to their energy efficiency, compact design, and ease of integration with centralized or standalone HVAC units.

Partnering with Avnan gives you access to innovative, customizable and robust circuit board designs. We also offer a full range of complementary assemblies for fan coil units, such as wall mounted display units, transformers, thermistors, power cords and wire harnesses. Our fan coil controller solutions are designed for flexible OEM integration, supporting advanced communication, control features, and reliable HVAC performance.

Let us help you create smarter and more efficient HVAC solutions that set your product apart in a competitive market.

Fan coil operation demands precise control of airflow, temperature, and energy consumption, requiring advanced control circuit boards and temperature sensors to enable valve actuation and variable speed operation of the fan motor. The fan coil controller integrates advanced sensing, communication, and control technologies to improve efficiency, reliability, and system performance. Additional capabilities, like automatic fault detection and alerts make these units unique.

Key functions and features of a fan coil control unit:

• Controls EC motors by PWM or analog voltage 0-10V, monitoring their speed
• Controls multi-speed PSC motors
• Works with 2, 3, 4, or 6-pipe systems for heating and cooling using on/off or modulating actuators
• Multi-inputs for various sensors such as: temperature, relative humidity, Indoor Air Quality, water leak, condensation overflow
• RS-485 Communication Port
• Optional opto-isolator module for ECM control
• BACnet for Building Management systems (BMS)
• Compatible with most standard thermostats
• BLE app for troubleshooting

These HVAC diagnostic solutions help technicians quickly identify system issues while giving OEMs better visibility into product performance.

We specialize in designing and manufacturing high-quality and cost-effective PCBAs to meet unique demands, offering features such as integration with smart thermostats and fan operation based on real-time input from sensors and user commands. Our embedded control solutions enable OEM customers to develop flexible HVAC systems with customizable firmware, communication options, and intelligent control capabilities.

Our fan coil main control board features Wi-Fi and wireless communication with integrated BACnet capabilities, making it an ideal solution for modern HVAC environments and versatile applications. In addition, it also provides options to control a multi-tap PSC motor and multi-valve actuators.

This capability allows for real-time monitoring and efficient interaction with other subsystems, providing streamlined operation and maximum energy savings. As an advanced fan coil controller, the platform supports connected HVAC applications with improved monitoring, control, and diagnostic functionality.

Wireless connectivity gives technicians insight into the system and helps to diagnose system problems quickly and efficiently. The integrated HVAC monitoring system delivers real-time system information, helping technicians improve troubleshooting accuracy and reduce service time.

Avnan’s BLE app includes troubleshooting guides which can provide real-time data for temperature, fan speed, valve position and system status with current operating mode for technicians to identify and resolve any problem with the system. These smart diagnostic features support smart HVAC solutions by improving system visibility and simplifying maintenance workflows.
